hi guys i just got my 81 3.8 cutlass up and running for the first time in a while.. only problem is i have check engine light flashing.. it seems to run fine all the way until you start to pull up a hill and it has a hesitaion problem.. runs and drives perfectly fine until then.. its not every hill either.. just like 4-10 probably does anyone have any idea on what this could be ? i was thinking egr valve maybe? or throttle position sensor if this has one.. thanks any help is appreciated

Start simple, when's the last time it had a new fuel filter?

What trouble codes are there? Have you jumpered it out yet to retrieve them? For whatever it's worth, GM C and H bodies with the 3800 can have this issue when the torque converter locks up and there is weak spark. I've owned a few of them with high mileage and have corrected the issue with new plug wires.
